Police warn 900 Calais migrants could be reaching Britain EACH MONTH

SEVEN out of 10 migrants camped in Calais could be getting into Britain, police have warned.

As many as seven out of ten migrants could be entering the UK, a police chief says

With an estimated 5,000 desperate migrants now massed in the northern French town, groups of refugees are storming the Channel Tunnel each night as well as smuggling their way into UK-bound cars, lorries and trains in the port.

Kent Police's chief constable Alan Pughsley has now claimed as many as 900 migrants could be crossing the UK border and entering Britain illegally each month.

He said: "Having consulted with our French colleagues, they have confirmed that through their own research, 70 per cent of migrants they process in the area of Calais leave the vicinity within a four-month period.

"They cannot ascertain whether these migrants leave to go elsewhere in France, or whether they enter the UK."

Assuming migrants don't give up on reaching the UK after trekking thousands of miles from war-torn Africa or the Middle East to reach Calais, it means as many as 10,500 could be entering Britain over the course of a year.

Between Monday and Thursday last week, there were 5,000 attempts to enter the Channel Tunnel from the French side, while figures show there were 2,157 arrests of suspected illegal immigrants in the UK in the first six months of the year - up from 1,836 from the same period last year.

The situation at Calais is part of a 'global migrant crisis'

There are two reasons why Calais is full of migrants. One is that Britain is regarded as a soft touch and the other is that they are getting through.

Lord Green, the chairman of campaign group Migrationwatch, said: "There are two reasons why Calais is full of migrants. One is that Britain is regarded as a soft touch and the other is that they are getting through."

Over the weekend, Calais deputy mayor Emmanuel Agius warned he will tear up the Anglo-French treaty that means immigration checks take place on the French side of the Channel rather than in the UK.

Threatening to open the border at Calais and "let the migrants through", he warned David Cameron: "They will be on his territory, in the port of Dover.

"He poses as the saviour of the situation, on a subject he is greatly mistaken about."

Graffiti sums up how many migrants feel

Despite the mounting chaos in northern France, the Government has refused to blame the French for the crisis.

Home Secretary Theresa May issued a joint statement with her French counterpart Bernard Cazeneuve, in which the pair called for other EU members to help address the root causes of the crisis.
